Legacy systems

Modernize legacy systems step by step.

We modernize business-critical legacy systems step by step so they become fit for current requirements again without putting ongoing operations at risk.

Business-critical legacy systems

Your system keeps the business running and blocks change at the same time.

Many legacy systems are business-critical but no longer fit for current requirements. They carry day-to-day operations while slowing down speed, maintainability, and change.

Security gaps

Expired libraries and outdated runtimes create attack surfaces that are increasingly hard to close with conventional patching.

Slow delivery

Every change requires regression testing across the monolith. Product ideas quickly turn into infrastructure projects.

Hiring bottleneck

Aging Java stacks make critical roles harder to fill and concentrate knowledge in a few long-time team members.

Maintenance cost

A large share of the budget is spent preserving the status quo instead of enabling new features and sustainable decoupling.

Step by step

Modernize one step at a time.

We modernize the part of your legacy system that has the biggest leverage today. After every step, you decide how to proceed.

01

Clarify priorities

We identify the part of your legacy system that should be modernized first.

02

Modernize selectively

We modernize exactly that part so it becomes productive quickly and relieves pressure on the overall system.

03

Continue step by step

After each step, you decide what should happen next based on clear, evidence-based progress.

Each step improves the system without turning it into a risky big-bang project.

Case study

What step-by-step modernization looks like in practice.

Using Apache OFBiz as an example, we show how a business-critical part of a legacy system can be modernized step by step.
